Modern casino slot games are controlled by computer software, and the win percentages are preprogrammed into the gaming software.
Casino slot machine games have RNGs which are constantly generating combos, even when the game is not active.
Running in sync with the random # generator of the casino slot machine is the pay out percent.
The payout percentage controls how much the one-armed bandit will payout, for e.g. the payout percent may be 90%, meaning the slot game will pay out ninety per cent of all the wagers played, and the casino simply gets to keep ten percent.
This really does not mean that each and every time you bet ten credits you will receive 9 in return – where’s the fun … excitement in that? Instead, the casino slot machine just won’t payout for a little while, and then suddenly hit a hot streak and you might draw the big grand prize.
The payoff percentages shall vary between the various games and several of the highly acclaimed casinos, e.g. Golden Online Casino, which gives a pay out of up to ninety five per cent!
This means that, in essence, the slot machine game takes all the $$$$$ played into it and pays it out to some chosen winners. The casino only gets to keep a fairly small % of all the odds allocated.
The casino slot machine software controls each part of the machine, from the dazzling lights to the rolling of the reels.
When you hit spin on the slot machine game, a combination is produced by the RNG which corresponds to the pictures on the reel.
